Definitions

  • the invention relates to a method for generating a colored decorated injection molding.
  • the aim of the invention is to provide a method with injection molded parts of high physical and chemical quality can be produced with a good aesthetic effect.
  • the colored one Decoration in particular should have a high strength and give a high-quality visual impression.
  • thermoplastic Soften plastics thermoplastics, plastomers
  • piston spraying machine the material heated and, pre-plastified by pistons, through channels or Nozzles pressed into a cooled mold.
  • the material is evenly plasticized by a screw and achieve a very homogeneous temperature distribution, the worm acts like a piston and the tool fills.
  • thermoplastic materials come in Consider, in particular polycarbonate and particularly preferably polymethyl methacrylate (PMMA).
  • PMMA polymethyl methacrylate
  • Particularly preferred as a film material is a so-called ethylene-styrene interpolymer (ESI, a Manufacturer's name DOW-Chemical). This slide is a co-polymeric polyolefin.
  • the layer thickness of the plastic film is preferably 50 ⁇ m to 500 ⁇ m.
  • the color decor by means of the so-called "release” technique from a carrier to transfer to the plastic film mentioned.
  • EP 0 573 676 A1 describes the use of a carrier "Release" property for applying color decor to a Substrate.
  • This state of the art is used for this purpose the color decor on a carrier with "release” property applied, then over the applied to the carrier Color decor applied a varnish, the lacquer then partially cross-linked and then under pressure and / or elevated temperature partially cross-linked paint with the color decor from the carrier to the ultimately to be decorated substrate transferred so that the paint under the color decor on the substrate.
  • the lacquer then partially cross-linked and then under pressure and / or elevated temperature partially cross-linked paint with the color decor from the carrier to the ultimately to be decorated substrate transferred so that the paint under the color decor on the substrate.
  • Carriers with "release” properties are known as such (see EP 0 573 676 A1).
  • certain papers are particularly considered or also plastic films that are designed on their surface or are prepared that applied under certain conditions Layers of paint or varnish in the manner of a "Peeling" (like a decal) on an object or a Are transferable.
  • a carrier with "release” property plastic films into consideration, such as in particular polyester films.
  • peeling off is also suitable Release layers for the film with "release” property known.
  • Diffusion of the dye molecules of the color decor is preferred at temperatures from 180 ° C to 300 ° C, depending on the used Plastics.
  • the color diffusion takes place both in the plastic film (e.g. PMMA) as well as in the back-molded Plastic.
  • the color diffusion creates a depth effect the resulting colored decor of the injection molded part, because the dye molecules, depending on the molecular weight (color), different Diffuse stretches in the plastic. This results in an aesthetically appealing, high-quality decor.
  • the temperature increase can, at least in part, already during of back injection or after.
  • the paint is preferred colored, d. H. it provides a base color for the injection molded part.
  • the paint is over the color decor and under the color decor is the plastic film, i.e. H. the paint is directly facing the injection molding material. The paint therefore gives the injection molded part the color and this basic color the diffusing color decor is superimposed, the more or diffuses less far into the overlying plastic film.
  • a plastic film 10 is in the illustrated embodiment Made of polymethyl methacrylate (PMMA).
  • the plastic film 10 has a layer thickness of 50 ⁇ m to 500 ⁇ m.
  • On the plastic film 10 becomes a color decor 12 made of diffusible dye molecules applied.
  • the application of the color decor 12 on the plastic film 10 is done with the aforementioned "Release” technique.
  • the color decor 12 is first on printed a polyester film (not shown).
  • the polyester film has good "release” properties.
  • the color decor 12 will then from the polyester film to the plastic film 10 according to FIG. 1 Transfer “peeling" (release).
  • Plastic film 10 is in an injection molding device according to FIG 2 clamped. Only the plastic film 10 is shown in FIG. 2 and drawn the color decor 12, the lacquer layer 14 is the For the sake of simplicity omitted in the drawing, but it is actually exist.
  • the injection molding device has a feed hopper 16, in the thermoplastic material 20 in a known per se Way is entered.
  • the injection molding device has one Piston 18 which is movable in the direction of the arrow.
  • the Injection molding compound 20 is in a channel 22 in the figure from the left conveyed to the right, using a heating medium 24 kept at the injection molding temperature.
  • the injection molding compound 20 is injected through a mouthpiece 26 into molds 28, 30.
  • This Injection molding technology is known as such.
  • In the form 28, 30 is the plastic film 10 with the decor 12 thereon and the supported paint layer 14 supported.
  • the injection molding compound 20 is injected behind the film 10 and so produces that color-decorated injection molded part, in the illustrated embodiment the injection molded part is bowl-shaped and the colored decoration only on the inner surface of the bowl.
  • the process is suitable for producing injection molded parts, which are optionally decorated in full color in the manner described are.
